Symmetric-key algorithm — Symmetric key algorithms are a class of algorithms for cryptography that use trivially related, often identical, cryptographic keys for both decryption and encryption.The encryption key is trivially related to the decryption key, in that they may … Wikipedia
Symmetric space — In differential geometry, representation theory and harmonic analysis, a symmetric space is a smooth manifold whose group of symmetries contains an inversion symmetry about every point. There are two ways to make this precise. In Riemannian… … Wikipedia
Symmetric polynomial — This article is about individual symmetric polynomials. For the ring of symmetric polynomials, see ring of symmetric functions. In mathematics, a symmetric polynomial is a polynomial P(X1, X2, …, Xn) in n variables, such that if any of the… … Wikipedia
Symmetric bilinear form — A symmetric bilinear form is, as the name implies, a bilinear form on a vector space that is symmetric. They are of great importance in the study of orthogonal polarities and quadrics.They are also more briefly referred to as symmetric forms when … Wikipedia
Symmetric derivative — In mathematics, the symmetric derivative is an operation related to the ordinary derivative.It is defined as::lim {h o 0}frac{f(x+h) f(x h)}{2h}.A function is symmetrically differentiable at a point x if its symmetric derivative exists at that… … Wikipedia

Skew-symmetric graph — In graph theory, a branch of mathematics, a skew symmetric graph is a directed graph that is isomorphic to its own transpose graph, the graph formed by reversing all of its edges. The isomorphism is required to be an involution without any fixed… … Wikipedia
Weakly symmetric space — In mathematics, a weakly symmetric space is a notion introduced by the Norwegian mathematician Atle Selberg in the 1950s as a generalisation of symmetric space, due to Élie Cartan. Geometrically the spaces are defined as complete Riemannian… … Wikipedia
Semi-symmetric graph — In mathematics, a semi symmetric graph is an undirected graph that is edge transitive and regular, but not vertex transitive.In other words, a graph is semi symmetric if each vertex has the same number of incident edges, and there is a symmetry… … Wikipedia
Skew-symmetric matrix — In linear algebra, a skew symmetric (or antisymmetric) matrix is a square matrix A whose transpose is also its negative; that is, it satisfies the equation:: A T = − A or in component form, if A = ( a ij ):: a ij = − a ji for all i and j .For… … Wikipedia
Complete homogeneous symmetric polynomial — In mathematics, specifically in algebraic combinatorics and commutative algebra, the complete homogeneous symmetric polynomials are a specific kind of symmetric polynomials. Every symmetric polynomial can be expressed as a polynomial expression… … Wikipedia
